Guerrilla suggests Killzone 4 may be a PS3 game

There has been, before now, unsubstantiated talk of Killzone 4 as a PlayStation 4 game. But now developer Guerrilla has poured cold water on that theory.

There are three games being made by Guerrilla, revealed art director Jan-Bart van Beek at GDC this week, reported by IGN. They are Killzone Vita (Sony Cambridge), a new IP and "continuing the franchise on PlayStation 3".

However, van Beek didn't specify that the PS3 Killzone project was Killzone 4 - he could be alluding to DLC.

Were Killzone 4 to be a PS3 game, it would be the third Killzone game released on that platform.

Strike Killzone 4 from the PlayStation 4 'possibles' list, and that leaves Sony studios such as Naughty Dog, Media Molecule, Sucker Punch, Evolution and the Sony X gang - London, Liverpool, etc.. We don't know what Sucker Punch will follow InFamous 2 with, nor do we know what Media Molecule or the Uncharted team at Naughty Dog are up to.

Guerrilla's new IP is also a mystery. Jan-Bart van Beek said 32 ideas for it were whittled down to four, according to IGN - and the original list included themes like zombies, werewolves and steampunk. One steampunk Sherlock Holmes-fighting-Frankenstein-monsters idea turned into a '70s-punk game named Dark Science, where hero Jake Crowbar fought monsters as if he were Dirty Harry.
